![]() +5V output: the +5V connector pin is the same voltage seen by the microcontroller. The Rugged MEGA can supply power to shields or external circuits in three ways: The Rugged MEGA utilizes a 5V switching regulator for efficiency and a 3.3V linear regulator for noise suppression. This behavior is the same as the Arduino Mega. When more than one power source is present, the automatic power switching circuit selects external power (DC power jack or Vin, whichever is higher) when available, otherwise USB power is used. Please note that V- is Ground and V+ is Voltage In. Vin: this connector pin can either source power to the MEGA (3.5V-30V) or draw power from the DC power jack. This power input is also protected by a 500mA PTC. A 500mA PTC (resettable fuse) protects the computer from overcurrent.ĭC power jack: a 2.1mm center-positive DC power adapter can supply 3.5V - 30V. USB port: 5V is provided directly from the USB port. The MEGA is powered from one of three sources: ![]() Either file will function perfectly with the Arduino environment. This in return will make the MEGA show up in the device manager with said name. This driver is the standard FTDI driver, but has been modified so the the descriptor is Rugged Circuits Ruggeduino MEGA. It will automatically pick up the FTDI drivers from the normal windows driver finder, but will show up as USB to Serial Converter.Īn optional driver file is available by clicking this link: MEGA Driver File. ![]() The MEGA will show up in the device manager as "USB to Serial Converter". Drivers can be found directly on the FTDI website. The Rugged MEGA can be purchased on the MEGA Product Page. ![]()
